The range extender version of the i3 would be more along the lines of the Volt but not exactly. Rex i3 after initial launch, main market: US.

i8 system is still being tweaked so it will be interesting to see the final outcome. Whether the electric can be used as a push to pass, as well as final output numbers. They were deputing adding a limited slip and other performance driving. It is still a ways away from production so a lot can change.... it was originally a diesel!

Yes, the i3's range extender is *like* the volt but again not exactly. Supposedly the i3's range extender will be a small 600cc two cylinder that will only sustain the battery's charge once it hits a certain low point. The volts gas engine can, in some condition's deliver power to the wheels. BMW has claimed the i3's range extender will have no physical connection to the wheels and will only act as a generator.
